Customer Password
Control Password
The drive firmware allows activating and deactivating the write protection
for parameter values by means of three hierarchically different
passwords:
• Customer password
The parameter values of a parameter group combined by the
customer can be protected.
• Control password
Parameters protected by a customer password can be written;
"administration parameters" remain write-protected.
• Master password
All parameters that can be written, including "administration
parameters" and parameters protected by a customer password, can
be changed.
Note: The customer password can be defined by the customer, the
control password and the master password are defined by the
manufacturer!
• S-0-0192, IDN-list of backup operation data
• S-0-0267, Password
• S-0-0279, IDN-list of password-protected operation data
• P-0-4064, Password level
Functional Description
The activation and deactivation of the write protection for parameter
values by the three hierarchically different passwords is carried out by an
input in parameter S-0-0267, Password.
By a password defined by the customer, the parameters of a parameter
group to be defined can be protected against unauthorized or accidental
write access.
The customer password has to comply with the following conditions:
• at least 3 characters long
• a maximum of 10 characters long
• may only include the characters a...z, A...Z and the numbers 0...9
The group of parameters the values of which can be protected by the
customer password is defined in parameter S-0-0279, IDN-list of
password-protected operation data. In the condition as supplied the
parameter S-0-0279 does not yet contain any data. In the list parameter
S-0-0279 it is possible to enter parameter IDNs according to application-
specific requirements.
Note: The customer password is not obligatory! If it has not been
activated, the values of the parameters listed in the list
parameter S-0-0279 can still be written.
After entering the firmware-specific control password defined by the
manufacturer, it is also possible to write parameters protected by a
customer password. The control password therefore allows the NC
control unit to ignore the write protection established by the individual
(unknown) customer password.
